An infinitely long line of charge has linear charge
Chapter 23, Problem 30E(choose chapter or problem)
An infinitely long line of charge has linear charge density 5.00 × 10?12 C/m. A proton (mass 1.67 × 10?27 kg, charge + 1.60 × 10?19 C) is 18.0 cm from the line and moving directly toward the line at 1.50 × 103 m/s.(a) Calculate the proton’s initial kinetic energy. (b) How close does the proton get to the line of charge?

An infinitely long line of charge has linear charge density 5.00 × 10?12 C/m. A proton (mass 1.67 × 10?27 kg, charge + 1.60 × 10?19 C) is 18.0 cm from the line and moving directly toward the line at 1.50 × 103 m/s.(a) Calculate the proton’s initial kinetic energy. (b) How close does the proton get to the line of charge?
ANSWER:Solution 30E Step 1 of 6 : 12 In the given problem, a long line of charge has linear charge density = 5 × 10 C/m. 27 19 A proton with mass m = 1.6p × 10 kg and charge q = 1.6 × 10 C is a=18 cm from the line and moving towards with initial speed v = 1.5i× 10 m/s. 3 Here we need to calculate the (a) initial kinetic energy of proton ,KE =and (b) how i close the proton can get into the line of charge b= Given data, Linear charge density, = 5 × 10 12 C/m Mass of proton, m = 1.67 × 10 27kg p 19 Charge of proton, q = 1.6 × 10 C Initial position, r i18 cm=0.18m Initial speed, v i 1.5 × 10 m/s To find, (a) Initial kinetic energy of proton, KE = i (b) how close the proton can get into the line of charge b=
